How the iMessage black dot bug works

Previously, we came across the black dot bug that crashed WhatsApp on Android smartphones. Though WhatsApp on iOS was purportedly immune to this bug, it seems like the stock iMessage app is not.

As soon as you click on the message, the iMessage app will hang and become totally unresponsive.
